You can read the ruling here:
“The constitutional right to bear arms in public for self- defense is not “a second-class right, subject to an entirely different body of rules than the other Bill of Rights guaran- tees.” McDonald, 561 U. S., at 780 (plurality opinion). We know of no other constitutional right that an individual may exercise only after demonstrating to government officers some special need. That is not how the First Amend- ment works when it comes to unpopular speech or the free exercise of religion. It is not how the Sixth Amendment works when it comes to a defendant’s right to confront the witnesses against him. And it is not how the Second Amendment works when it comes to public carry for self- defense.
New York’s proper-cause requirement violates the Four- teenth Amendment in that it prevents law-abiding citizens with ordinary self-defense needs from exercising their right to keep and bear arms. We therefore reverse the judgment of the Court of Appeals and remand the case for further pro- ceedings consistent with this opinion.”
